Sleep duration and risk markers for type 2 diabetes: a cross-sectional study in children aged 9–10 years

Shorter sleep duration has been associated with obesity, increased cardiovascular morbidity, and mortality in adults and with obesity in children. However, effects on childhood risk markers for cardiometabolic disease have been little studied. We examined associations between self-reported sleep duration and cardiometabolic risk markers in children and whether sleep duration might explain ethnic differences in insulin resistance.
